Advanced Materials Interfaces, Volume 12, Issue 10, May 19, 2025.Pump‐probe shadowgraphy of glass drilling is shown with a femtosecond laser operating in MHz‐ and GHz‐burst regime. A comparison with standard femtosecond micro‐processing using repetitive single pulses is provided. The ablation plume lifetime is measured in all three regimes, and the drilling dynamics of Through Glass Via (TGV) in GHz‐burst mode are ...

Ecology and Evolution, Volume 15, Issue 4, April 2025.Urbanization fragments habitats and isolates populations, reducing gene flow and driving divergence in genetic, acoustic, and morphological traits. Over ten years, isolated populations of white‐eared ground‐sparrows exhibited increased inbreeding, altered song characteristics, and changes in body and beak size, with significant correlations found ...

Theory of the Cutter-Oscillators Design
Shock and VibrationIn this study, a theoretical analysis was conducted on the design of the cutter-oscillators with a single-degree-of-freedom and a two-degrees-of-freedom, where the resulting direction of deflection of the cutting edge aligns with one of the inertia axes ...

Measurement of dynamic characteristics of technological system
Trudy Odesskogo Politehničeskogo Universiteta, 2016 It is overview of the measurement methods of free oscillations of console tools and forced vibrations during cutting. Non-contact inductive and capacitive sensors are commonly used for such measurements. Often used measurement methods are using inductive
